Some people will cross the Potomac River via water taxi on Inauguration Day.

WASHINGTON (CNN) - While nearly all maritime activity on the Potomac River will be halted on Inauguration Day, a handful of Mall-goers will sail from Virginia to Washington on water taxis.

Working closely with the United States Coast Guard, the Potomac Riverboat Company, based in Alexandria, Virginia, plans to ferry up to 3,200 passengers from across the frigid Potomac on seven climate-controlled boats.

The service is partially a response to the closure of all bridges from Virginia to D.C. on Inauguration Day, a measure that prompted an uproar among Virginia residents.

According to maritime authorities in charge of the region, PRC is the only company being allowed to taxi across the river on the 20th.

"Because the taxi service provided us with a security plan that we examined and deemed adequate to provide good security, I granted them a waiver to operate at an increased security level," National Capitol Region Port Captain Brian Kelley says.

"The taxis are going to operate on a strict schedule and a strict route."
